I think it's hard to overestimate how big an achievement this is in itself. Managed by Q is going after a market dominated by ISS [1],a Danish company founded in 1901, with more than half a million employees and revenue around $75 billion. And its doing it by paying proper salaries.
The market is very interesting because and the potential for expanding into new categories and with a more modern approach to facility management.
I could imagine them getting into using drones for surveillance or even automated green areas management. It's a field I believe is pretty well defended by the incumbents but which can be disrupted using a combination of technology and more on demand services to drive down cost and increase profitability without actually having to treat it's people like uber drivers.
On top of that it has revenue and is solving a real problem.
